- Abstract
- The role of a modern librarian has become more and more demanding in the information age. One of the new challenges for the information specialists is what's usually called "the teaching librarian", meaning that the librarian or information specialist should be able to teach at least basic practical searching skills to the patrons in need for relevant information. Query Performance Analyser (QPA) is a tool for analysing and comparing the performance of individual queries. It has been developed in the department of information studies at the University of Tampere. It can be used in user training to demonstrate the characteristics of IR systems and different searching strategies. Usually users can't get any feedback about the effectiveness of their queries and therefore may have difficulties to perceive the actual fectiveness of a query formulated, or the effect changes between queries. QPA provides a instant visual feedback about the performance of a given query and gives the user a possibility to compare the effectiveness of multiple queries and the performance of different query formulation strategies. QPA is based on predefined search topics. They all contain a corpus of documents that are relevant to the given topic. The purpose of this paper is to give a brief insight to the infrastructure of QPA, the basic :Functionality of the QPA-based game, and to its implementation in IR education.
